Yes, that is true of a sitting “President”. However there remains the question of how one is removed if they are not legally President to begin with?
It really does not matter WHERE Barack Hussien Obama aka Barry Soetoro was born. His father was not a US citizen at the time of Obama’s birth. If Obama was born in Hawaii he is a US citizen but STILL not a “natural born” citizen.
Folks, this isn't even a close question. There isn't a "How to remove a President if he shouldn't have been seated in the first place" clause in the US Constitution.
Impeachment and only impeachment is the "removal tool" bestowed upon the Congress. SCOTUS has no power, either implicit or explicit, to remove a President once he's been sworn in. Any conjecture to the contrary is pure folly.
Amen. Somebody who knows shirt from shinola.
